Be it known that 1, Crane NEWELL CASS,

a citizen of the United States, and a resident of Spangle, in the'county of Spokane and acute an best resu ts inworking the ground, t e draft being central in'both cases, and also exceed State of Washington, have invented a new and Improved. Disk Harrow, of which the following tion. 7 j K The pur ose of the invention is toconstruct a dlS lK harrow or similar implement in two sections, a forward and a rear section, and providing means whereby the sections can be adjusted inde endently or relatively to each other and he d in adjusted position, the parts being released" for adjustment by the driver butthe actual adjustment being performedtby the team.

A further purpose of the invention is to provide a simple, durable and economic constructi'on that will enable the tooth or disk carrying members of each. section to be brought into parallelism for the purpose of travelingto and from the field, or placed at 'les to each other to accom lish the is a full, clear, and'exact descriphe invention consists in the novel construction and combination of the several parts, as will be'hereinafter fully set forth and pointed out in the claims. I Reference is to be had to the accompanye ing drawings forming a part of this specification, in which similar characters of reference the tion, one section having disk cutters and the .indicate corresponding parts in allthe fig? ures.

Figure 1 is a plan view of the implement,

arts being inposition for travel ng to and horn the field,both sections of the implement being shown provided with disk 'cutillustratmg the twojsections in working posiother being. provided withteeth; Fi .3 is" a plan viewof an implement of the kin shown in' Fig. 1,illustratin the first step for the ad- I 'justment of the im ementfrom the lposition illustrated in said 1g. 1 F g.4 is ap an view of the implement of the tipe shown In Flgs. 1 and 2, and illustratm t jworkingposition'; and i 5.is a detail sectional view taken practica yon the line 5- 5 of Fig. 2.

The implement is made in two sections a forward section'A and-a" rear section B, WhlOh e parts therebf in.

sections are coupled togetherin a removable manner. In the construction shown in Figs. 1, 3 and 4 the disk cutters are employed in both sections. In the construction of the forward section A a body beam 10.is em ployed, from which an axle 11- is supported by means of suitable hangers 12, the upper ends only whereof are shown, and disk cut-' ters 13 are mounted upon said axle, being spaced apart in any approved manner. -An arched bar 14 is secured to the body beam 10, the side members of said frame being at equal distances from the center of said beam;

and the right-hand limb 14 of the arched frame is made to extend beyond the rear edge of the body beam 10. An arched frame 14 is provided with a recess 15 at the-central portion of the inner ed e of its'forward or bowed member, and a second recess or notch 16 to the left of the central recess 15. A tongue or pole 17 is pivoted to the central portion of the body beam 10, the rear end 18 of which pole or beam extends about the same distance to the rear of the beam 10 as does the aforesaid limb 14 of the arched frame 14; but the pole 'or tongue 17 is independent of the said archedframe 14. a A guide barv 19 is pivoted to the rear portion of the ole or tongue 17 and is adjustable upon t erear. extended portion of the arched frame 14, the outer end of said guide bar, which engages with said limb 14*" of the frame, being provided with a slot 20, which pivot the guide bar 19 is capableof correspondmg movement- A cross bar 22 is secured -to thesaid tongue, extending an equal distance beyond each side thereof, the center of said cross bar being the pivot point of the tongue. The tongue is made to carry a spring-controlled latch 23, and said latch is adapted to enter either-one of the recesses'15 or 16 of the arched frame-14.

The rear section B also consistsiof a body beam 10", an axle 11 supported by suitable bearin s 12* and disk cutters 13 mounted on-sai axle; and said body bar-1O is also provided with an attached arched frame 14*,

sustaining the same relation to the body beam or bar 10 as does the. arched frame .14 to the forward bodybeam 10. The forward or curved portionof the" arched frame 14 is provided with a central recess 15 in its inner edge, and witha recess 16 corresponding to tion.

'section.

the recess 16 of the forward section; but the recess 16 is to the right of the central recess 15 instead of to the left as in the front secsaid -rear body beam 10*, and said reach carries a spring-controlled latch 25, corresponding to the forward latch 23 and adapted to enter either of. the recesses or 16; and the reach 24 also supports the drivers seat 26, to which, or to a point within easy reach of the seat, chains or links are carried from the latches 23 and 25, enabling the driverto operate either one or both, as may be necessary.

A slide 27 is hinged or pivotally attached to the forward end of the reach 24, and said slide 27 is ada ted to travel freely on the guide bar 19. hains 28 and 29 are attached to the ends of the cross bar 22, carried by the pole or tongue 17, and these chains extend rearward and are adjustably attached to keepers 30 of any approved type, located at the forward end portions of the side members of the rear arched frame 14.

In .Fig. 2 the rear section B consists of a toothed harrow, in which construction a front beam 31 is provided and bars 32 extend from therear edge ofsaid beam 31, being hinged thereto. The bars are preferably four in number,.each pair of pivoted bars being connected by a series of tooth carrying bars 33, so that the rear section B is constructed of two sub-sections. Links 34 are secured to the beam 31 at equal distances from its center, and said links are connected with an eye 35, which eye is in its turn connected with a slide 36, adapted to travel u on the guide bar 19'of the front N desire it. to be understood, however, that any e uivalent of the rear harrow section B may e attached to the forward section A, without departing from the spirit of the invention.

In operation, when the machine is to be adjusted from its arrangement for transportation shown in Fig. 1 to anarrangement for service in the field as shown in Fig. 4, the right-hand chain 28 is tightened up, the latches 23 and 25 are withdrawn from engagement with the arched frames 14 and 14. and the team is turned to the left, whereupon the osition of the parts will be that .shown by ulllines in Fig.3. Then the team is turned to the right until the pole or tongue- 17 is again centrally placed and in consequence the twosections A and B of the harrow will be brought at an acute angle to each tral notch 15 of the forward section A and A reach 24 is centrally pivoted to the.

'of the latches, and that the body beams of the two sections A and B may be made to converge at the left-hand side of the implement instead of at the righthand side if so desired.

In Figs. 2 and 5 I have illustrated a con struction whereby a low draft im lement may be attached to the section A, an wherein an arched U-frame 37 is secured to the axle 11, at its ends,'as is shown at 38 in Fig. 5, and a draft bar 39 is secured to the slide 36, and said bar has an attached slide 40 at its lower endv mounted upon the U-frame 37. A sleeve 41 is adjustably mounted u on. the draft bar 39, being held in osition y a setscrew or its equivalent, an the connecting medium for the attachment is received by said sleeve Having thus described my invention, I
